+I run this configuration mostly on Mac OS X, so we need a couple of

+`exec-path-from-shell` is included (only if you're running OS X), this is
+to include environment-variables from the shell. It makes useing Emacs
+along with external processes a lot simpler. I also prefer using the
+`Command`-key as the `Meta`-key.
